Left ventricular remodelling after myocardial infarction involves maladaptive responses. Key factors include mechanical overload, fibrosis, and cell death, potentially influenced by cardiocyte modifications.

Area of Science:

  • Cardiology
  • Pathophysiology
  • Molecular Biology

Context:

  • Left ventricular remodelling is a complex process following myocardial infarction.
  • It manifests clinically as systolic and diastolic dysfunctions and arrhythmias.

Purpose:

  • To propose a framework for understanding cardiac remodelling.
  • To identify the core biological paradigms driving these changes.

Summary:

  • Cardiac remodelling is driven by maladaptive responses to mechanical overload.
  • Fibrosis, stemming from senescence and ischemia, and cell death (necrosis/apoptosis) are key contributors.
  • Phenotypic modifications in cardiocytes due to ischemia or hormones may also play a role.

Impact:
